DuPont’s Q4 figures beat expectations despite slipping slightly as a result of declining volume. The company reported net income for the quarter of $373m compared with $376m for the same period in 2011. The chemicals giant reported full-year earnings of $3.5bn. “We delivered exceptional full-year results in 2011 despite significant market headwinds late in the year,” said DuPont CEO Ellen Kullman. “Our market-driven science continues to meet customer needs in food, energy and protection”.
